Condition or disease

Intervention/treatment

Phase

Occluded Totally Implanted Central Venous Catheter

Drug: Ascorbic Acid

Phase 2

Detailed Description:

Totally implanted catheter is often occluded and thrombolytic drugs are usually used to restore permeability. In Brazil, the ascorbic acid has been used successfully by a service specialist in cancer treatment. However, no literature on international research that evaluates the efficacy and safety of this procedure. That was why it was decided to develop this research.
